did you
know... LET'S say you are in plane flying westward around the Earth's equator. At the equator, the time zones are a little over 1,000 miles apart, so to cross one every hour, your plane will have to fly at over 1,000 miles per hour . If you started flying at 12 noon, at 1 p.m. you will cross a time zone, making it 12 noon again. This process will continue for as long as you stay in air: As soon as the hand of your watch crosses 12:59, you’ll have to turn it back to 12:00 again. For your entire westward trip around the Earth, the time will range between 12:00 noon and 1:00 p.m. What you are really doing is flying at the same speed at which the earth is rotating, but in the opposite direction, so the sun is always in the same part of the sky. What if your plane could stay in the air for days, or even weeks? Would time stand still for you? The answer is that the time of day would always be the same, but the date would continue to change. The time would always be between 12:00 noon and 1:00 p.m., but each time you crossed the International Date Line, it would instantly become 12:00 noon of the next day — Compiled by Gaurav Sood |
